is this HT&L or not? i think something may be overrunning its bounds


phreak (developer)

i figured this may also be attributed to v-sync not being enabled


Kazan (developer)

is this fixed?


phreak (developer)

i saw it in non-HTL mode, but it works perfectly in HTL


Kazan (developer)

pls fix it in non-htl and close the bug :D


phreak (developer)

ok i looked into this and it happens if missile trails come close to the player's view point in non-htl mode. I'm thinking its possible some miscaclulated screen coordinates when the trail goes through the non-htl functions


phreak (developer)

hmm this is an old one.

anyone still having problems?


taylor (administrator)

It's still happening but I haven't been able to come up with a fix. Don't really care to spend much time working on it either.


kasperl (developer)

Are we even supporting nohtl anymore?If not, this should just be closed.


Goober5000 (administrator)

It might be a good idea to maintain a certain amount of support for compatibility purposes.


taylor (administrator)

non-HTL is broken at the moment btw. I found that out last night when testing some things. Bobboau's geometry_batcher kill the g3_draw*() stuff since it can send too many verts through at the time.


phreak (developer)

close as nobody gives a damn? :p. Haven't noticed this in ages either.


kasperl (developer)

Well, if nohtl is broken, there's hardly any point in fixing this, but I'd rather leave this one open until there's either a fix, or an order from above (Goob, Inq?) to drop nohtl.

since we're ditching non-HTL, and the fact that non-HTL is broken anyway, can i just close this?

taylor (administrator)

Well, I think I've got the non-HTL crash problem properly fixed now (just adjusted the interp_allocate stuff to also handle this). I guess that all that's left for this is to give it proper clipping, since it doesn't have any currently. Bobboau just basically didn't do this right. But I can't say that I'd personally be all that thrilled to go in and make the drawing and clipping functions properly handle tristrips.

Unless someone else is willing to do that then I say we close this because it's not worth messing around with. It's a minor graphical glitch which just isn't that annoying and almost no one is going to see at this point.


taylor (administrator)

Well, I don't care, and apparently neither does anyone else. I'll close this for now then and if I ever get the desire to try and track this down again I'll take another look at it. If I can't figure it out then both of those people who prefer to use non-HTL mode on every Feb 29th will just have to deal with it.
